摘要

对水中存在的农药和药物进行时空监测需要严格选择要分析的基质。使用分离或组合的基质,可以更好地代表污染的真实状态。在这个意义上,目前的工作对比了使用活性水采样和被动采样器pocis的上鳃生物膜的有效性。对南美洲农业流域代表进行了监测。对9个具有不同农村人为压力(天然林、密集使用杀虫剂和动物粪便)和没有污水处理的城市地区进行了监测。在大量施用农药和动物粪便期间,收集了水和石蜡生物膜。春夏作物收获后,农用化学品投入较低,使用POCIS和外缘生物膜监测农药和药物的存在。现场水取样导致对水资源污染程度的低估,因为它不能区分农村地区不同的人为压力。使用内源性外生生物膜作为分析农药和药品的基质是诊断水源健康的一种可行和强烈建议的替代方法,特别是如果与POCIS的使用有关。

Epilithic biofilms, POCIS, and water samples as complementary sources of information for a more comprehensive view of aquatic contamination by pesticides and pharmaceuticals in southern Brazil.

Spatial-temporal monitoring of the presence of pesticides and pharmaceuticals in water requires rigor in the choice of matrix to be analyzed. The use of matrices, isolated or combined, may better represent the real state of contamination. In this sense, the present work contrasted the effectiveness of using epilithic biofilms with active water sampling and with a passive sampler-POCIS. A watershed representative of South American agriculture was monitored. Nine sites with different rural anthropic pressures (natural forest, intensive use of pesticides, and animal waste), and urban areas without sewage treatment, were monitored. Water and epilithic biofilms were collected during periods of intensive pesticide and animal waste application. After the harvest of the spring/summer crop, a period of low agrochemical input, the presence of pesticides and pharmaceuticals was monitored using the POCIS and epilithic biofilms. The spot water sampling leads to underestimation of the level of contamination of water resources as it does not allow discrimination of different anthropic pressures in rural areas. The use of endogenous epilithic biofilms as a matrix for the analysis of pesticides and pharmaceuticals is a viable and highly recommended alternative to diagnose the health of water sources, especially if associated with the use of POCIS.
